Using sds, sample the data at the time of new and periodic vehicle inspections.
After saving the sampled data in the computer, file them by model and by user.
The periodically filed data help improve the accuracy of troubleshooting since they can indicate the condition of vehicle functions that has changed with time.
For example, when a vehicle is brought in for service but the troubleshooting of a failure is not easy, comparing the current data value to past filed data value at time of normal condition can allow the specific engine failure to be determined.
Also, in the case of a customer vehicle which is not periodically brought in for service with no past data value having been saved, if the data value of a good vehicle condition have been already saved as a master (std), comparison between the same models helps to facilitate the troubleshooting.

Sample
Data sampled from cold starting through warm-up
Data at 3 000 r/min under no load
Data at the time of racing
Data of intake negative pressure during idling (100 °c)
Data of manifold absolute pressure operation at the time of starting
Example of trouble
Three data; value 3 (current data 3), value 1 (past data 1) and value 2 (past data 2); can be made in comparison by showing them in the graph. Read the change of value by comparing the current data to the past data that have been saved under the same condition, then you may determine how changes have occurred with the passing of time and identify what problem is currently occurring.
Note with dtc not output, if the engine idling speed and isc valve stepping position are found to be abnormal than the data saved previously, the possible cause may probably lie in the hardware side such as isc valve air inlet hose crumple, bend, etc. |
Injection timing description
Injection time (injection volume)
The factors to determine the injection time include the basic fuel injection
time, which is calculated on the basis of the
intake air pressure, engine speed and throttle opening angle, and various
compensations. These compensations are
determined according to ...
Ect sensor inspection
Refer to “dtc “c15” (p0115-h/l): ect sensor circuit malfunction” in section
1a .

remove the ect sensor. Refer to “ect sensor removal and installation” .
Connect the ect sensor (1) to the circuit tester and
place it in the o ...
Front suspension adjustment
After installing the front fork, adjust the spring pre-load
and two kinds of damping force as follows:
Adjust the
left and right front forks to the
same setting.
Spring pre-load adjustment
Turn the spring pre-load adjuster (1) counterclockwise
fully. From that position (softe ...
